Calculation Method for Load Data
Quote from Ryu on 13. August 2025, 12:39Hello Developers,
I am contacting you because I have a question while using the QBlade program.
I would like to know the complete set of equations used to extract load data during structural analysis in the program.
Could you please explain what methods and formulas the program uses to operate and perform these calculations?

It is not feasible to present the complete set of equations used in QBlade’s structural analysis here, as the implementation involves a large number of coupled aerodynamic, structural, and numerical formulations. These equations are spread across multiple modules and are tightly integrated with the Project Chrono structural solver.
For a comprehensive understanding, I recommend consulting the publications on QBlade and Project Chrono, which describe the underlying theory and numerical methods in detail:
Project Chrono publications: https://projectchrono.org/whitepapers/
QBlade publications: (see the Publications section of this website)
Additionally, the complete implementation can be reviewed directly in QBlade’s open-source code, available in the Downloads section.
Best regards,
David
